IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 38,157, dated April 14, 1863.

To a/ZZ whom it may concern:

Be it known that I, E. ELLIOTT, ot Petaluma, in the county of Sonoma and State of California, have invented a new and Improved Pump; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, Inaking a part of this specication, in which- Figure l is a side elevation of Iny invention; Fig. 2, a vertical central section of the same, taken in the line :v fr, Fig. l.

Similar letters of reference indicate corre spondin g parts in the two gures.

This invention relates to an improved suction and force pump 5 and it consists in constructing the same in such a manner that it will be capable of' being very readily applied and adapted in all cases where apnmp ot' this class is required, and at the same time beexceedingly simple, not liable to get out of repair, and admit of being manufactured at a small cost.

To enable those skilled in the art to fully nnderstand and construct my invention, I will proceed to describe it.

A represents the induction, and B the eduction, passage ofthe pump, which are formed 4by simply boring longitudinally rectangular pieces a, of timber ot' any suitable length, and connecting the same together by metallic thimbles b, inserted in the ends ofthe pieces, the latter being prevented from splitting by ferrules c.

C is an air-vessel, constructed of metal, and communicating with the eduction-passage B at any proper point by a horizontal tube, el, as shown in Fig. 2.

D is the pump-cylinder, open at its lower end and closed at the top. This cylinderA is of cast metal, and has a iat plate or iiange, c, at one side, which is cast with it, and has two holes, ff, in it, which communicate with the interior of the cylinder. The plate or ilange e is bolted to one ofthe pieces, a, which has the upper end of the induction-passage A init and the lower end of the eduction-passage B, the latter being curved at its lower end so as to be brought in line with the hole f, and the upper end of the induction-passage A being curved so as to be brought in line with the holes j".

E E are valves, which may be formed in a piece of leather, g, corresponding in area to the plate or flange e of the cylinder D, the plate or flange being fitted on or to the leather, so that the latter will answer as a packing, as well as for the forming of the valves. The lower'valve, E', opens inward or toward the pump-cylinder, while the upper valve, E, opens outward or into the eduction-passage A. The lower valve, E', closes against a perforated metal plate, h, fitted overthe upper end ot' the inductionpassage A.

F is the piston or plunger, which is fitted in the cylinder D, and is connected by a rod, i, to the lower end of a yoke, G, which extends upward above the cylinder D, and is connected by a rod, H, to a handle or brake, I. The rod H is connected to the yoke G by means of a dovetail slit-joint, j, encompassed by a rin g or band, k, as shown clearlyin Fig. 1.

From the above description it will be seen that by operating the brake I the piston F will be raised and lowered in the cylinder D. Each time the piston descends the valve E closes and valve E opens, anda suction is produced in the upper part of the cylinderD into which the water from A passes, and when the piston F descends the valve E closes and valve E opens, and the water in the upper part ot' the cylinder is forced into the eduction passage B and out at its upper end.

The endsof the pieces a, which form the induction and eduction passages, may be Iirmly secured together by wooden cleats l l, attached by screws or bolts to the end ot one piece, and having a metal stra-p, m, iitting over them at their free or disengaged ends, where they clasp the adjoining piece, c. (See Fig. l.)

The piston F, it will be seen, works entirely below the valves E E.

By this combination and arrangement of parts a very simple and cheap pump is obtained. It may, by adding more or less pieces a, be adapted to wells of any depth, and the cylinder D may be either submerged or not, as occasion may require.

I do not claim, separately, any of the parts herein shown and described; but

I do claim as new and desire to secure by Letters 'Patent- The forming of the induction and eduction tlbes A B of a series ofwooden pieces, a, bored longitudinally, and connected together, substantially as shown, in combination with the pumpcylinder D, attached to one of said pieces a and communicating with the tubes A B, as shown, and provided with the piston F, all arranged to operate as described, the

above parts being used with or Without the air-vessel C.
